Affine-Scaled Attention: Towards Flexible and Stable Transformer Attention

ICML 2026poster

Transformer attention is typically implemented using softmax normalization, which enforces attention weights with unit sum normalization. While effective in many settings, this constraint can limit flexibility in controlling attention magnitudes and may contribute to overly concentrated or unstable …

SelfJudge: Faster Speculative Decoding via Self-Supervised Judge Verification

ICML 2026poster

Speculative decoding accelerates LLM inference by verifying candidate tokens from a draft model against a larger target model. Recent "judge'' decoding boosts this process by relaxing verification criteria by accepting draft tokens that may exhibit minor discrepancies from target model output, but e…

CLARA: Classifying and Disambiguating User Commands for Reliable Interactive Robotic Agents

RA-L 2024

In this letter, we focus on inferring whether the given user command is clear, ambiguous, or infeasible in the context of interactive robotic agents utilizing large language models (LLMs). To tackle this problem, we first present an uncertainty estimation method for LLMs to classify whether the comm

SPOTS: Stable Placement of Objects with Reasoning in Semi-Autonomous Teleoperation Systems

ICRA 2024poster

Pick-and-place is one of the fundamental tasks in robotics research. However, the attention has been mostly focused on the "pick" task, leaving the "place" task relatively unexplored. In this paper, we address the problem of placing objects in the context of a teleoperation framework. Particularly,…

Visual Preference Inference: An Image Sequence-Based Preference Reasoning in Tabletop Object Manipulation

IROS 2024poster

In robotic object manipulation, human preferences can often be influenced by the visual attributes of objects, such as color and shape. These properties play a crucial role in operating a robot to interact with objects and align with human intention. In this paper, we focus on the problem of inferri…
